so worth it for the quality!

i've tried hanro before but zimmerli is just another level. i finally treated myself to one of their cotton nightshirts, the one with the classic collar, and it's ridiculously soft. shipping was pretty fast, got here in like 4 days, and it came nicely packaged. i just wish they had more sales, i missed the last seasonal one but i'm hoping for a welcome discount pop-up soon for some cashmere loungewear. i'm still a little nervous about washing the sea island cotton though, trying to figure out the best way to keep it perfect.

Got my sleep mask

Needed a new sleep mask, so I checked out Zimmerli. Ordered one, and it showed up pretty quick. It's soft and does the trick, blocks out the light and feels nice on my face. Easy peasy.

Decent quality, minor issue

I purchased a pair of modal trunks. The material is very comfortable and they fit well, true to size. Delivery was prompt, arriving in about 4 business days. My only minor gripe was that one of the seams seemed a little less reinforced than I'd expect for the price point, even on sale. It's not a dealbreaker, and they're still very wearable, but it was noticeable. Overall, a good experience, just a tiny room for improvement on the finish.

Consistent quality always

I've been buying from Zimmerli for a few years now, mostly for their Richelieu tank tops and Royal Classic t-shirts. This latest order, a Royal Classic t-shirt, was just as good as all the others. The material holds up well over time and washes nicely. It's why I keep coming back; I know what I'm getting and it's always reliable. Never had an issue with any of my orders.

Good value for quality

I bought a pair of Pureness boxer briefs during their seasonal sale. I had heard good things but wasn't sure about the price. Getting them with a discount made it much more appealing. The quality felt really good, definitely a step up from what I usually buy. It felt like a smart purchase given the savings.

Love my new pajamas!

I just got the silk pajamas and they are absolutely amazing! So soft and luxurious, I felt like royalty the moment I put them on. The fit was perfect too. I'm already thinking about what I'll buy next, maybe some loungewear. I've told my sister about them already, she needs to get some!

Smooth order, nice item

I ordered a Sea Island Cotton undershirt. The website was easy to navigate and the checkout process was straightforward. Shipping took about 6 days to get to my place in California, which was within the estimated window. The undershirt itself is very soft, just as described. The stitching looks solid, and it's comfortable to wear all day. I haven't needed customer support, so I can't comment on that, but the overall experience was positive.

Hey all, does anyone know if Zimmerli does those Black Friday sales? Been eyeing some silk pajamas but the price tag is a bit oof. Wondering if it's worth waiting.

K Kate 2 months ago
They definitely do! I got some loungewear during their Black Friday sale last year. It was a good chunk off, like 30-40% on certain collections I think.

Yes, they participate in Black Friday. It's usually an automatic discount applied to select items, so no need for a code or anything. You might get a newsletter sign-up discount too if you haven't already.

Thinking of finally splurging on some Zimmerli stuff, probably the Sea Island cotton. How does the sizing usually run for their undershirts? True to size or should I go up/down?

E Elena 2 months ago
From my experience, their undershirts are pretty true to size. I wear my usual t-shirt size and it fits perfectly, not too tight or baggy.

Yeah, I'd say stick with your normal size. I got a Richelieu tank a few months back and it fit exactly as expected. They're meant to be a bit snug without being constricting, at least the ones I have.
